Revealing mistake: When Graham and Stella are in bed, the camera shows only their arms intertwined as if he's lying on top of her. She's gasping loudly in response to his thrusting, but their arms never move back and forth to reflect this, so it's clear they're not really having sex.
Melanie O'Conner: I think it's rotten, Mr. Marshall. The only reason you didn't get that job is 'cause they didn't give it to you.
